gathered around the point of the accident or were otherwise dis- 
tracted from their work. The number averaged 9 men per accident. 
The 689 noninjured workers were away from their work 447 hours. 
This means that each accident cost the company approximately 6 
hours of productive time other than the time lost by the injured. 
Analysis by Departments—One of the measures of the severity 
of an injury is the amount of time the injured loses from his work.

ever, they resulted in a loss of but 19 per cent of the total time lost. 
The machine-shop accidents were relatively less severe than those 
occurring in other departments, as they caused a loss of but 12 hours 
per accident, whereas those of the foundry resulted in an average 
loss of 161 hours, and those of the forge shop 97 hours per accident. 
Foundry accidents composed 8 per cent of the total number of acci- 
dents, and accounted for 40 per cent of the time lost. 
In 72 injury cases, the noninjured were involved to the extent of 
an average of 60 men per accident in woodworking plants; 11 in 
foundries; 8 in chemical plants; 6 in storeroom, warehouse, and yard 
group; 4 in machine shops. 
The average number of productive hours lost per accident by the 
noninjured was 24 in woodworking plants; 8 in chemical plants; 4
